Explicitly call pip2 rather than pip in locations where both pip2…

… and pip3 are installed (sonic-net#5747)

As part of the transition from Python 2 to Python 3, we are installing both pip2 and pip3 in the slave and config-engine containers. This PR replaces calls to `pip` in these containers with an explicit call to `pip2` to ensure the proper version of pip is executed, no matter which version of pip is aliased to `pip`, as we no longer rely on that alias.

Also some other pip-related cleanup
